Thunder of the Night Sky (夜天の雷 Yaten no Ikazuchi) is a [[:Special:Ask/-5B-5BCategory:Spells-5D-5D-20-5B-5Bspell-20category::-5D-5D-20-5B-5Bspell-20type::-5D-5D|wide-area space attack]] spell used by Reinforce in The Battle of Aces and The Gears of Destiny as her Full Drive Burst. Apparently it has similar effects to Diabolic Emission. Reinforce strikes her opponent with a compressed black sphere of energy, causing it to expand to surround both characters and remain at a fixed size. She then fires a bolt of white lightning at her opponent, causing the sphere to shatter.
